By custom each size of ring book binder has a standard diameter of wire for each diameter of ring., and a standard spacing for the rings. Each size or" sheet of ring book paper has a standard punching, and the diameter of the holes corresponds to the rings for -one inch ring books. When, therefore,

the number of sheets exceeds the capacity of a one inchring book, two or more books must be used because the punching of theI paper prevents the sheets being transferred to a ring book of larger capacity.

An eiiort to overcome this limitation' has been made by the use of tongue books equipped with adjustable screws, but while this construction can be made to take any number of sheets the operation of inserting or removing the .sheets is so tedious and time consuming that people of the type usually in charge of such books will notv keep vthem posted up to date.

The object ofthis invention is'to provide a binder that will take standard paper and permit the capacity to be varied to suit conditions and the Isheets to be removed or inserted with ease and celerity.

The fundamental organization `includes two separable binder bars equippedl with two sets ot posts, one set to extend through the perforations inthe paper and the other set to bind the bars together and furnish the strength to the binder. The posts of the first set are relatively small and, being liXed close to the margin, can be received in the holes in the paper and will permit the book to be opened wide. The posts of the other set are large and are made of such size as is necessary to hold the binder bars in proper relation and relievethe smaller posts from strain. These large posts are spaced back from the margins `or the paper and have no effect upon the punching oi' the paper.

Other objects and advantages of the in-v vention will become apparent as the description proceeds and the description is read in connection with the accompanying drawings, in which,

Fig. 1 is aplan view of a binder embodying the invention, with certain parts l'at the upper side broken away;

through adiiferent form of lock bar;

Fig. 7 is a longitudinal horizontal section vthrough the same;

Fig. 8 is a view similar to Fig. 1, illustrating another form vof binder embodying the invention Figs. 9` and 10 are longitudinal and transverse vertical sections taken on the lines 9f9 and 10-10 of Fig. 8; and i Fig. 11 is a vertical sectionalview of an extensible post thatfmay be used in connection withthe structure shown in F igs.v 6 and 7.

In these drawings a bundle of'sheets to be .bound is shown at 10, between lthe leaves 11 and 12 of a cover, which are hingedly connected to the binder structure composed generally of upper and lower binder bars 13, 14, equipped with a set of small telescopingposts 15, and a set of large strong posts 16, which latter cooperate with a lock bar 17 to hold the bars 13, 14, in binding relation to the sheets 10.

An angular plate 18, secured to the binder bar 14 by the riveted bases of the posts 16, has anv upright portion 19 shielding and protecting the rear edges of the sheets 10 and cooperating with the lock bar 17 to give the binder a linished appearance. The covering material for the cover leaves is made to extend over the angular plate 18, as'indicated at 20,

andthe locking bar 17, as indicated at 21.

The large posts 16 are reduced near their ends at- 22 to cooperate with a locking slide 23, slidably mounted in the hollow lock bar 17 and moved into engagement with the posts by a screw 24 rotatably engaged with the slide and threaded in a nut 25 carried by the lock bar. The lower wall 26 of the lock bar is perforated at 27 to receive the upper ends of the posts and to bind against them when the latch bar is properly moved by the screw 24. Eis shown, the locking slide is provided with openings 28 larger than the posts, whereby it is adapted to pass freely over the posts in being put in place or removed.

The posts 15 are relatively small as compared with the posts 16, and are preferably composed ot inner and outer telescoping sections A and B, the former being carried by the upper binder bar 13 and the latter by the lower binder bar 14. These posts can be made to suit any size of punching, and will be suiiiciently strong in the selected size to retain within the binder a very large number of sheets, since most of the strain of holding the binder parts in proper relation will fall upon and be taken by the large posts 16.

lVhen it is desired to lill such a binder the screw 24 is operated to move the locking slide 23 to released position, when that bar, with the lear" 11 and the binder bar 13, with its posts A, are removed. rl`he sheets are placed upon the posts B, the binder bar 13 and the i lock bar 17 are replaced, and the lock made fast.

lWhere found desirable this binder can be made eXtensible or adjustable by making the large posts 160 adjustable, as indicated in Fig. 5. The base section 29 is substantially the same as the post 16, except that it has no reduction corresponding to that shown in Fig. 2, and is provided with a threaded socket 30, which will receive a threaded stem 31 on a removable head piece 32, or any of a selected number of intermediate pieces 33. The telescoping posts 15 are inherently adjustable, and will permit the capacity of the book, equipped with such posts as shown in Fig. 5, to be varied widely.

In Figs. 6 and 7, the lock bar 34, corresponding to the lock bar 17 shown on sheet 1, is equipped with a different locking mechanism, including tilting latch pieces 35, nor" mally held in the position shown in Fig. 6 by springs 36, but capable of being thrown upwardly to released position by inclined surfaces 37 on a releasing bar 38 slidably mounted in the lock bar and controlled by a handle 39. rllhe latch pieces are perforated, as indicated at 40, to receive the upper ends of the large posts 41, which require no reduction. When the latch pieces are permitted to take the normal inclined position, they immediately bind against the posts and secure the lock bar in place. Upon bringing them into a substantially horizontal position in Fig. 6, they release the posts and permit the lock bar to be removed.

rEhe posts 41 may be made sectional, as indicated in Fig. 11, where the base portion 42,

fined to the lower binder bar 14, may receive Y a threaded shank 43 on a head section 44, and a tubular intermediate section 45 may be mounted on the threaded shank 43 when desired.

In the form shown in Figs. 8, 9 and 10, the upper and lower binder bars 13 and 14 are each secured to an angular bar 46 by the riveted bases of the telescoping posts 49 and the lock post 50, the upright portions 47 of which lie alongside of each other and together close the rear face of the binder mechanism. These pieces are enclosed within the covering material 48 and connected with the leaves 11 and 12 of the cover.

r1`he posts 16 of sheet 1, and 41 of Figs. 6 and 7, are replaced by a set of telescoping posts 49, each composed of an outer tubular portion C, carried by the lower binder bar, and an inner portion D, carried. by the upper angle member 4.6 and extending through the upper binder bar into telescoping relation with the section C. rlhe upper angle member 46 corresponds to the look bars 17 and 34, and therefore is a lock bar. rlhe posts 49 are large and strong as compared with the posts 15. The perforations in the upper binder bar 13 rit snugly about the post sections D and communicate any stress on that bar directly to the large strong posts.

"ihe'lower binder bar carries an additional lock post 50, threaded internally to receive a long screw 51, having a head 52 for cooperation with a latch 53 slidably mounted on the upper angle piece 46 by headed pins 54, which extend through slots 55 in the latch. The intermediate portion of the latch has a keyhole slot 56, cooperating with the head of the screw to lock or release the parts in an obvious manner. By adjusting the screw 51 the capacity oi: the binder can be varied to suit conditions.

Generally speaking, the length of the post sections A. and B, C and D, and the upright flanges 47 of the angle pieces, will be made to correspond and to permit adjustment within selected limits. ln this form the upper angle member 46 corresponds to the lock bars used in the other forms.

lt will be noted that in all forms the separable binder bars are equipped with one set of relatively small posts which extend through the perforations in the sheets, and are set near the front edges of the binder bars so as to permit the book to be opened wide. ln addition the binder bars are equipped with a large strong set of posts which serve to take the strains that would otherwise be too much for the small posts vVith such a construction sheets of paper having the standard punching for one-inch ring book binders can be used in any suitable quantity and can be readily removed and replaced.
